Application filed February 5, 1891. Serial No. 380,388. (No model.)

To aZZ whom it may concern: handle or lever Qwhich controlling-handle is Be it known that I, JONATHAN O. FOWLER, fulcrumed at c to the top of the standard or J r., a citizen of the United States, and aresipost a and serves upon manipulation to dent of New York, county and State of New cause the upper arm A to approach the lower 55 York, have invented a certain new and usejaw A.

The jaws A A may by being the cutter E, in cases where a collar is used, grasped directly by the hand be caused to ap and, the instrument being held in one hand I00 proach eachother; but for convenience Ipreand the glass to be out being inserted bei'er to use in connection with the same a tween the parallel or approximately parallel therein, whereupon by slightly knocking or jarring the same the portion of the glass desired to be removed will fall off, the separation having occurred on the line previously marked by the rotary cutter E.

It is obvious that either one of the arms or jaws may be stationary, as in Fig. 1, or that both of the same may be adapted and ar-' ranged so as to have some movement, as in Figs. 2 and 3, or that, if preferred, the two jaws may normally lie close together, as in Fig. 4, and be pulled apart to admit of the entrance of the glass between the same, in which case the two jaws will recede from eachother and again approach one another, maintaining all the while a parallel or approximately parallel relation to each other; or, if so desired, the handle may be attached to one of the movable pins, as represented in Fig. 5.

As it is evident that many slight changes in the construction and relative arrangement of parts might be resorted to without departing from thespirit and scope of my invention, I would have itunderstood that I do not restrict myself to the particular construction and arrangement of parts shown and described, but that I reserve the right to make such changes, and that l/Vhat I claim as new, and desire to secure by Letters Patent, is-

1. A hand glass-cutter consisting of two arms or jaws, one provided with a cutter and the other adapted to serve as a rest or clamp for the glass and arranged to reciprocate, in combination with means forholding the same in a practically parallel position, the two jaws being adapted and arranged upon manipulation to maintain a parallel relation while one arm is moving to and from another or both arms are moving to and from each other, substantially as described.

2. In a hand glass-cutter, the combination, with the two arms, one carrying a cutter and the other a rest for the glass tubing and arranged to reciprocate, of the vertical guides for preventing the arms getting out of the same plane with one another, substantially as described.

3. In a hand glass-cutter, the combination, with the two arms, one carrying a cutter and the other a rest for the glass tubing and arranged to reciprocate, of the vertical guides and springs, substantially as described.

4. In ahand glass-cutter, the combination, with the two arms, one carrying a cutter and the other a rest for the glass tubing and arranged to reciprocatev and to approach and recede from each other parallel, of an auxiliary mechanical device applied upon or connected to the aforesaid arm or arms for operating an arm or arms, substantially as described.

5. A glass-tube cutter comprising an arm with a cutter at one end, said arm being attached at or near the other end to another arm carrying a suitable bearing opposite the cutter of the first arm, the bars being so connected as to permit movement toward and from each other and having an auxiliary connecting device connected to or bearing upon each bar and with a projecting lever-handle, whereby the bars maybe pressed toward each other during the cutting, substantially as described.

In testimony of the foregoing specification I do hereby sign the same, in the city of New York, county and State of New York, this 8th day of January, A.D. 1889.
